Improvement in heating-stoves



UNITED STATES PATENT OEETCEQ SAMUEL SMITH, OF PHILADELPHIA, PENNSYLVANIA.

IMPROVEMENT IN HEATING-STOVES.

Specification forming part of Letters Patent No. 55,728, dated June i9, 1866.

To all whom it may concern:

Be it known that I, S. SMITH, of Philadelphia, Pennsylvania, haveinvented an Improvement in Stoves; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the may be transported with less danger ot' injury j than those of ordinary construction.

My invention further consists ot the combination, with the above, of a base-plate having openings so arranged as to prevent the ashes from escaping from the interior ot' the cylinder onto the exposed portion of the baseplate.

In order to enable others skilled in the art to make and use lny invention, I will now proceed to describe its construction and operation.

On reference to the accompanyingdrawings, which form a part ot' this specification, Figures 1 and 2 are sectional elevations ot' sufficient ot' a cylinder-stove to show my improvement, and Figs. 3 and 4 are plan views ot' parts of the stove.

In the ,upper base-plate, A, of the stove is a central opening, X, and round the edge of the latter is the usual annular ilange a. On the base-plate, a short distance from the tian ge to, is an annular rib, 0, which is concentric with the dan ge, and between the two are openings w, for a purpose described hereinafter.

B is a metal ring, the upper edge of which is in contact with a shoulder on the sheet-iron body or cylinder D ot' the stove, the lower edge ot' the cylinder being bent outward so as to project below the inner edge ofthe ring, ns shown in the drawings, the body and ring being thus firmly secured together.

In the plate A are two openings, l d, each of which is larger at one end than at the other, and on the under side ot' the ring B are two lugs, e e, the ends of which project beyond the edge of the ring, for a purpose described hereinafter.

At the side of the ring B are four projections,t' i t t, each of the projections i fi. being adjacent to one of the lugs e, while each of the projections t" t" is perforated to permit a screw, s, to be passed through the same into an opening, t, in the base-plate.

When the body is to be secured to the baseplate the ring B is brought over the plate and the lugs e c are passed through the large ends of the openings d d. The ring is then turned in the direction of the arrow, Fig. 3, when each lug c will be brought to the small end of the opening d, the projecting portion of the Ing extending beneath the plate A, thus preventing the ring from being raised from the same, while the projections t' t extend over and cover t-he large ends ofthe openings d d. lhe screws s are now passed through the lugs t" t" into the base-plate, the ring being thus both secured at the opposite side and prevented from turning.

In stoves of the ordinary construction the lower edge ofthe sheet-metal cylinder tits over the iiange a, and sometimes, when the stoves are to be transported any distance, is secured to the iiange by means of ,metal rivets. As the cylinder is but little larger than the ange, it is frequently a matter ot'fdii'ticulty to tit the two together, especially it' the cylinder happens to be detached after the stove has been used for a little time. After the stove has been in use a short time, also, the tine ashes frequently escape between the cylinder and the ilange a onto the base-plate and present an unsightly ln the above-described stove the cylinder may be readily and quickly attached to the ring, which is sufficiently rigid to prevent the cylinder from being bent at the edge during transportation, while the ring and base-plate may be secured quickly together without the necessity ot' employing skilled workmen. Should any ashes escape between the tla'nge a and the cylinder, they will fall through the openings :I: to the ash-box.

It will be apparent that the upper endot1 the cylinder may be secured in a like manner to the top plate or cap ot' the stove, and that constructed and adapted for attachment to the base or cap plate of a stove, substantially as described.

2; The combination, with the above, of the base-plate A, with its openings arranged as set forth, for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses. v

SAMUEL SMITH.
